Estimate the incremental cancer risk for a 60-kg worker exposed to a
particular carcinogen under the following circumstances. Exposure time is 5
days per week, 50 weeks per year, over a 25-year period of time. The worker is
assumed to breathe 20m3 of air per day. The carcinogen has a potency factor
of 0.02 (mg/kg-day)-1 and its average concentration is 0.05mg/m3. Average Life
is 70-year.
1year=365 day
